Direction of earth’s gravity
Scientific definitions of ‘up’ and ‘down’ We live on the surface of the Earth and are always under the influence of its gravity. When we let go of an object, it falls “down,” and when we … more
Blocklab – Biological Classification Coding
Blocklab – Biological Classification Coding Code the process of classifying biological organisms by assembling blocks. Enter the name of the organism you want to analyze below, then press the Enter key or click the Classify ⏎ … more
Blocklab – Circular motion simulation
This is a simulation of circular motion (orbital motion) of an object using Blocklab. You can experiment with object motion by applying various variations to the block code.
Blocklab – Parabolic motion simulation
This is a simulation of parabolic motion of an object using Blocklab. You can experiment with parabolic motion of an object by applying various variations to the block code.
Blocklab – Block coding tool
Blocklab is a simulation creation tool built on Google Blockly that lets users assemble blocks to explore a wide range of dynamic experiments. With Blocklab, you can create algorithm-based dynamic simulations intuitively. The simulations you build … more
Solar wind and the aurora
Solar wind The Sun emits electrically charged particles. Because the Sun is mostly hydrogen, these particles are mainly protons and electrons. They travel through space at hundreds of kilometers per second. When solar activity increases, the … more
Kinetic Molecular Model of Gases
Characteristics of Gases Unlike solids and liquids, gases have the following unique characteristics: 1. They have no definite shape or volume Gas particles move in all directions and can fill any part of a container. Therefore, … more
Solar System
Solar System All the orb bodies that revolve around the sun and their space are called the solar system. The celestial bodies that make up the solar system include the eight planets revolving around the sun … more
Mercury Barometers on Different Planets
What would happen if you brought a mercury barometer to Earth, the Moon, Mercury, Venus, and Mars? Here, we assume that the mercury barometer has a U-shaped tube: one side is open, and the other side … more
Spectrum Analysis of Sound
This simulation analyzes the sound around you and displays it as a spectrum. The simulation works by recognizing the surrounding sounds. In the case of PC, please grant permission to use the microphone. Voice data is … more
Density distribution in the atmosphere
Observe how the density distribution of the atmosphere changes as gravity (gravitational acceleration) is varied. The total kinetic energy of the air particles is assumed to be constant. Gravity is assumed to act uniformly, and no … more
